On a recent flight
over St. Louis,
I saw this view of the
Mighty Mississippi River.
. . . and saw this
"log jam" of coal barges,
loaded and en route to New Orleans.
A careful count (just in this single image)
shows 199 barges, waiting their turn,
to be "pushed" downstream.
Each barge carries 1500 tons of coal.
That's 298,500 total tonnage.
"Steam coal" destined for power usage
in Asia and Europe.
The Mississippi is the most economical
mode of transportation,
shipping coal to international customers.
That's a giant carbon footprint.
(Hopefully, we're coming to the end
of our dirty coal burning era.)
